3G connection frequently stops/hangs

Hi Folks,
I've had my SIMfree Desire for a few days now and since the off I've been having some problems with the 3G data connection.
No matter what app I'm in, though the signal meter shows I have a very strong 3-4 bar 3G connection, after a short initial burst of HSDPA the connection seems to just stall and hangs until I restart the connection. It does this in both my work and home cell zones some 40 miles apart so it doesn't appear to be a problem with the cell zone. Sometimes it'll clear and carry on quite quickly, other times I get bored of waiting.
It drives me nuts in the browser and Market where surfing becomes neigh on impossible. In other apps (Stocks, Friendstream/Facebook, News, Android keyboard, etc.) I can usually come back later and I may or may not be lucky.
Is anyone else experiencing this?
I am on Orange so I'd be grateful if someone who's on Orange with rock solid 3G performance could post/PM me their settings so that I can check mine - though I haven't messed with them.
Could an app be causing this?
Many thanks!
___________
Update: From posts here, and the experience of a mate with a Desire on Vodaphone, it seems that many others are experiencing this problem regardless of network.
I've had all my settings checked by Orange Tech Support and though they made some changes they made absolutely no difference.
I emailed HTC about this yesterday but when I get home tonight I'll be following that up with a phone call. Can we all do the same so they actually realise it may be a problem with the phone itself?
Cheers All!

I have the same issue too with my Orange handset, thought i was in a bad area at the time but maybe not.... hmmmmm.....

I got this issue yesterday as well
I tried to browse the internet via 3G ... and it just stucked ... only the "up arrow" were lighted (traffic up) ... but no traffic down.
The icon went from 3G then H ... then 3G ...
Very frustrating ...
But after about 5 minutes ... I was able to browse internet.
I hate this.
Unlocked, unbranded, htc retail version.

I have an unlocked Desire on Voda and it only loses connection when I *try* to send a picture message.
Could someone else try test this please?

It's happening for me too. Just got this yesterday and on the Vodafone network. This is the perfect phone for me, but with this hanging / drop out 3G issue is really frustrating. Hope HTC fixes this soon or i will be stuck with a lemon

So most of the posts here confirm that it is the phone and not the network, as there is another thread with T-mobile users have issues with 3G.

I saw that thread but didn't add to it. It does appear that it isn't just T-Mobile and my phone, but something that many folks are experiencing regardless of network or area.
From what I can read of the other thread it appears that T-Mobile are accept responsibility as a network problem but as others on other networks are seeing the same issues I'm not convinced it is a network problem.

I think you could be on the mark this one, now a few operators are running the handset the issue is becoming apparant not just on T-Mobile devices.
Certainly something that HTC needs to address. T-Mobile, Orange and Voda customers all experiencing the same issue.....hmmmmm

It is definitely a problem for more Desire owners. A bit anoying if you are a hardcore mobile Internet user. And indeed, sending a picture to Facebook is already too much over 3G.

Do you guys also have problems maintaining a connection? for example today my data connection disconnected twice.. The only way to get it connected again is by enabling and disabling airplane mode.

Ive had same problem on my hero but not noticed on my Desire, both are on orange, happens loads on Hero Orange not able to explain must admit i just live with it as like the phones so much.

My problem seems to be fixed. When I started using the phone out of the box my apn setting for Vodafone Australia had been detected. What I did to make it work, was that I deleted the apns and reentered from scratch. My 3g connection seems to be more stable and consistent now.

This happens on mine also, and I've used 3 operators, in UK and Australia. It just hangs the connection, so I just have to switch connection off or go airplane mode, it will then work fine for a while.

When you have this problem ... Did you see the "3G icon" keep changing to "H" (HSDPA) then "3G" then "H" ?
That was in my situation. It looks the phone cannot maintain its data connection.
When it works, it works and fast, either on "H" or "3G".
Note that I am checking this problem on the same location, at my home And it is covered by "H" (hence sometimes it works).
Could this be a problem on signal stability of the mobile operator/provider?
I am thinking to buy a prepaid from other mobile operator and test it.
PS: I am using T-Mobile NL atm, planning to test Vodafone NL prepaid.

I'ce been browsing the web for about half an hour.Uploading, downloading stuff.
No problems with the connection whatsoever.I live in Antiparos Greece and my provider is Cosmote.
I have a sim free, unlocked, retail HTC Desire running the latest firmware and stock settings.

I've noticed this as well, when it's on 3g I can't actually browse but on g or h then it's fine! I'm on t-mobile.

Not exactly what I want to hear
I have the exact same problem with my HD2 on TMOBILE UK and am getting the Desire tomorrow BECAUSE of this.
I REALLY hope it won't be the same case, in that case it's a common thing.
HD2 AND DESIRE both have this issue.

There is/was a well acknowledged issue with the Nexus One and 3G connection (on T-mobile) - search it on Google.
There's nothing so far (that I've read) that says it is definitely the phone or the network.

I have the same problems.
Please contact the HTC support about this issue, perhaps they will release a fix for it.

T-Mobile HDSPA

I noticed the other day that Paul from modaco posted that even though he lives in an area with NO 3G on any network all of a sudden he has 3G on T-Mobile.
In my home and surrounding areas i can only get GPRS. If i set my phone to force WCDMA it will never connect.
However after seeing Pauls post i tried again and now setting my phone to force WCDMA i can get one and two bars on HDSPA...
How very strange. It's great though because i use it for web browsing on my pc and i can download roms quickly enough.
Should maybe try a speedtest?

Pauls new coverage might be a side effect of the tmobile/three network consolidation/expansion. If he has tmob coverage now he probably has 3 too.

I've noticed a better signal recently - sometimes getting H at home. Can I ask which area of Hull you're in?

i've tried it and get 'H' at home now (liverpool city centre) with t-mob. although, i just gopt the 3GB pack turned on on Sun. was on the slower 1GB before that

T mobile are to start roaming on to the Orange network and vice versa as part of their merger which may have something to do with it.

Signal Issues, please help

Hi guys, just flashed a new rom (jm7).. everything went ok.. but when I rebooted I notice that I get just about no signal in areas where I used to before get full bars.
Tried going back to other rom's but no luck, I still continuously get a poor signal. One thing I did notice is that right after boot the signal slowly goes to 5 bars (even in areas with bad signal) and then slowly goes down to 0-1. This same instance happens when I place a phone call as well.
Any ideas? I can barely use data when this is going on as well.

Try going into mobile networks and network operators and see if there's a second option for your network. You might be connected to a weather signal. It's under wireless settings. Happened to me.

Are you sure that your network operator make some not some work on cell bt in your area? One time i have too like you bad and wrong signal, and make all with my galaxy, reboot,recovery, signal refresh app, APN point new entered, but still problem. After all, I call my operater and they say me:" Sorry , we make same work on cell base station in area your city !!! Sorry for bad signal, we busy to make repair speedy !!! "
Best regards

Sorry double post

Thanks for the responses... no go sadly.. tried switching the 3 different "bell" networks and only 1 allowed me to connect. As for signal str in area, a friend who has the same network has 4 full, while i only get 1
I've tried reformatting/reflashing/reseting and nothing has worked.. what am i missing?

Network Issue!

I Loose network signal anytime i switch to 2g/gsm only
I have tried reboots, resets, tried different roms, all other sim cards have this issue when i use them on my phone, im on the latest radio too. Dont know what to do now..
Any help would be appreciated.

The T989 might be incompatible with the 2G bands, are you using it in the U.S.?

Dont think so, it used to work before, then after some time i would have to turn off the data or reboot before i could switch, and now it just stopped working!
Not in the US tho

Possible fixes for this is flashing the latest radio, I believe it's UVMC6. Works fine with my phone (I live in Mexico and 2G works fine)
EDIT: Sorry, I realize that you have the latest radio, my bad
I remember I used to have this issue too, what fixed it for me is choosing manually my network operator, available in the phone network settings. It was either choosing manually or automatically, I can't recall which one I chose, but it fixed the problem. I now have it in automatic and it works and from time to time when I travel to the US close to the border, my phone cannot decide if it wants to go with T-Mobile or my network (Movistar) so I change it to manual and select Movistar and works just fine, so maybe all you need to do is change from Automatic to Manual, or vice-versa. Hope that can help

Hey,
I tried choosing manually, it did say it was registered on network, but that's it, signal bar remained empty and it still said emergency calls only. At times the signal bar fills up, but saids mobile network unavailable when I try to make a call.
Appreciate your assistance tho

I managed to make a log of when I switch to 2g, If that would be helpful

Wish I could help, but I don't know what to do anymore. Why don't you just stick to 3G? There are some places I can't use 2G so I switch to 3G, I just deactivate data when I'm not using it. I sometimes lose 2G signal too, but that's mainly because I am inside a building with thick walls or I simply don't get 2G signal, happens from time to time on certain places, like my old work place for example. I would either get low signal or no signal at all.
I wish I could help, but even I don't know what to do. Best of luck to you

Radio problems.

So, i'm in the UK with my nice shiny OP3 (on Three UK) - I am rooted with twrp, but same applies on stock.
The radio in this phone seems to prefer H+/3G to 4G, even though where i live, i have full bars on both. My nexus 5 always prefered 4G, and the OP3 is set to prefer 4G but 90% of the time drops to 3G/H+
Another interesting thing, if i use the testing menu to force LTE only, even if it's on 4G already, completely stops any signal getting through for a number of minutes until it decides to connect sometime later. I have full LTE signal in my room too.
Is this a radio problem that could be solved in the future with a software update? not seen anyone else with this issue!
FYI, when it is on 4G, it's super fast and stays connected until a reboot, where the whole process starts again

APN Is exactly the same as my nexus 5, and i even added a new one. Same deal.
I'm an IT Professional, just not a developer. i've done everything i can think of. 4G does work, but only when it wants to. My phone is also registered with my carrier correctly.

Bump on this anyone?

I am having a similar problem I guess. I have the dual sims installed and one sim randomly shows no range. Further, the network preference is not the way it is supposed to be - Chose it as 4G and if 4G is not detected it falls back to 2G.

I did notice when I do have LTE it's fine but it won't re lock onto LTE after a call on Three where it has to drop to H

I'm having a problem where the phone catches 4G+ "carrier aggregation" and it'll jump from to 4g+ to 4g and back to 4g+ really fast like almost flashing . And speed test are showing low numbers. T-Mobile USA.

Same here. Sometimes it just locked to 3g/h+ in a strong LTE area for no reason. I'm on stock oos with one sim and 1 apn. Sometimes I need to reboot the phone to get LTE back.
Sent from my Pixel C using XDA-Developers mobile app

I first put my sim into slot 1 when I first got the device, I was having the exact same issue. I found that the data priority sim, or if you only have one sim needs to be in sim slot 2.

Yes exactly. And even then it doesn't show up straight away despite 3/4 and usually full signal. Sometimes just putting it into standby mode and leaving it 20mins can sort it... Until I get another call lol. Wondering if it's just a software or firmware issue that could be patched. Lte is fine it's just never preferred despite the options being set

APN is not the universal response. Here he faces a problem of inaccurate network type choice, APN is only to have acces to internet through the provider's proxies. It's a radio problem clearly, the baseband is probably to be corrected by OnePlus.
It's really a strange thing to see those network type issues, MMS issues are still present after all those years.

This is what I thought. It's probably an easy fix for oneplus or rom developers. Custom radios are nothing new. Let's hope so anyway!

This is happening to me as well. I'm on three in a strong 4G area but it always prefers 3G it's so annoying hope it gets fixed soon.

i tested op3 with 3 different carriers
on two of them - lte no problem, instant connect...
on third sim - slow connection, frequent out of range. almost no lte.
tested third sim on iphone - instant lte connect, no problem.
seems like a incompatibility with an selected cellular operators.

Could be but I'm doubting it. OP3 Has full support at least for my carrier on both bands they use (3 & 20).. Never know, the devs here will figure it out if oneplus don't

Same issue here, have never got it to say 'LTE' for me since I got the phone, best it does is 4G whilst my Galaxy S5 would happily pickup LTE. Just wondering what UK users have there preferred network type set to? Mine is on GSM/WCDMA/LTE I assume that is right as that is what it went to itself and have tried LTE or LTE/WCDMA too.
